-large mud-sill, U, at the bottom. The caps E E have four iron rods,R R R R, fastened at each end of the caps E E, and extend from them down through each, end of the mudsill U. The box T is formed on the inside of the frame D, and there is a large iron shaft, S, which has' aplmiger, Z, fastened on its lower end. The upper end of the Ashaft S passes up through the cap O, and the lower end, with plunger Z fastened thereto, passes down inside `the box T. The shaft S has notches formed on each edge of it between the lianges e e, which the large jacks X X work in, for the purpose of 4 running the shaft S down. It also has anges ee formed on each side ofthe shaft S. Two of the anges, it', in each edge of the shaft S have notches formed on them for the purpose of running the shaft S up, which is effected by two little jacks, jj, audit is run down by two large jacks, X X. The jacks X X and j j are worked by the large double leverl? at the top of the frame D. The two little jacks 7' j are pivoted to the lever P on each side of the shaft S, the upper ends working in the notches formed in each edge of the anges i 'e'. The two large jacks X X are pivoted on-the under side of the large double lever P `at each side of the shaft S,

and work in notches formed in each edge of the shaft S between the angeszz. and anges e4 e for the purpose of running the shaft S X X and j j have arms formed on them, with elastic cords fastened thereto, for the purpose of holding the jacks close to the shaft S. The jacks are moved oi and on by levers fastened to the frame D, and are connected by ropes to the jacks. There are two half circles, A A, attached to each side of the large double lever P, which work against dogs N N. The dogs N N are placed in holes on each side of the shaft S. When one segment takes its hold the other segment is released. The segments A A are only used at ythe time the heavy strain comes against the jacks X X, and then they are used for the purpose of assistin g them. The twohalf circles or segments A A and the two large jacks X X are so constructed that both powers can be used at the same and at separate times.

What I claim as my improvement is- The combination in a baling-press, with the double lever P, jacks `X X and j j, notched shaft S, and follower Z, of the segments A A anl dogs N N, as and for the purpose specifle URIAH THREATV STEWART;
